Then tell us the version number of your ecu as I have shown above and attach a copy of your map and we will take a look.

V1.3 bottom board should be fine. Need to see your map. Ensure aux 4 is set to tacho and ensure no other aux, fuel or ign outputs are set to tacho.

So engine is running but tacho is showing 0? is Ignition Drive 5 set to Tacho?

Also, tacho is on a different aux depending on the bottom board revision number, you can find it where I have marked the pic below.
I dont remember exactly when the change was made, but if it is somewhere around V1.5 or lower then tacho is on Aux 4, newer versions tacho is on Ign 5.
